2 About company EKOTON INDUSTRIAL GROUP EKOTON Industrial Group is a leading manufacturer of equipment for wastewater treatment. EKOTON Industrial Group focuses in development, production and implementation of modern high quality technological equipment dedicated to municipal wastewater treatment as well as industrial applications in food process, cement, chemicals, coal and metal process enterprises. Our company produces more than 35 different types of equipment for mechanical treatment, biological treatment and sludge dewatering. A wide range of EKOTON brand products allows us to offer our customers complex solutions using equipment we produce. Our company s production plants are located in Poland, Ukraine and Russia. More than 300 highly qualified specialists of EKOTON Industrial Group work to provide high quality services and equipment. EKOTON equipment is successfully operated in more than 30 countries of the world 2 The total air flow rate fed to all EKOTON Air Diffusers in operation exceeds ft 3 /h

3 EKOTON provides up to 6 year warranty for the air diffusers, though the practice shows that they operate successfully after the expiry of the warranty period. EKOTON - PROFESSIONALS CHOICE 3

4 AERATION SYSTEMS on the basis of tube diffusers EKOTON Tube Air Diffusers were developed for application in municipal and industrial wastewater treatment plants. Their primary use is for supplying the required levels of oxygen to wastewater in the aeration tank while providing a highly efficient and economical mix of oxygen and wastewater in the aeration step of the treatment process. 4 The total air flow rate fed to all EKOTON Air Diffusers in operation exceeds ft 3 /h

5 Advantages of EKOTON Tube Air Diffusers Do not require cleaning and flushing.the porous external polyethylene layer with "fibro-porous" construction provides for tough, reliable operation of the aeration system without the need for routine cleaning and flushing. Effective mass transfer and sludge mixing. The bubbles which the EKOTON Air Duffusers produce have a diameter of only in which is ideal for oxygen transfer and mixing into the sludge mixture. Due to the internal perforated pipe and "fibro porous" design of the outer tube, the EKOTON Air Diffuser provides uniform air distribution over the entire area of the aeration tank. We are able to minimize and avoid pressure drops, water hammers and other mechanical issues. The EKOTON aeration system is easy to assemble with simple threaded components which are quick to assemble on the tank bottom in lengths up to 6.6 ft. The rate of air flow supplied to our EKOTON Tube Air Duffusers is times faster than conventional membrane diffusers. This provides for lower investment and capital costs on projects. Also due to the special design and engineering of the Ekoton Air Diffuser, we are able to reduced operating costs due to low pressure loss. Due to the use of the thermoplastic materials in their design, EKOTON Air Diffusers are resistant to a wide range of challenging environmental and temperature conditions. EKOTON Air Diffusers provide consistent, reliable and stable performance during their long service life. EKOTON - PROFESSIONALS CHOICE 5

6 Design of EKOTON Tube Air Diffusers The EKOTON Tube Air Diffuser is made up of two pipes inserted one into another with an air gap running between them. The outer pipe (disperser) is porous in construction and is made from low-density polyethylene (LDPE). It is the outer «fibroporous» pipe portion of the Air Diffuser. During manufacturing, a pneumatic extrusion process is utilized and aerodynamically formed fibers from melted polyethylene are applied to the outer pipe with a mold maker. The inner pipe is made from PVC and is also perforated. The gap between two pipes is supported by cross ring insertions which are integral to the air supply connecting to the air diffuser. The supply air enters the gap between the inner and outer pipes through the numerous hole openings in the inner supplyk pipe. The air is then dispersed into the aerated liquid through the outer pipes «fibro-porous» construction forming numerous and consistent bubbles. Forcing the air into the inner pipe and uniformly out through the «fibro porous» outer pipe provides a consistently uniform air distribution in the liquid you want aerated. This enables us achieve a superior aeration efficiency with minimal energy cost.

10 More than 500 water and sewage companies in 14 countries have chosen EKOTON Tube Air Diffusers. We offer our clients: Inspection of wastewater treatment facilities prior to the reconstruction (analysis of qualitative and quantitative composition of wastewater for the selection of the optimal treatment scheme); Individual approach to each facility, application of nonstandard solutions and various methods of installation; Selection of air diffusers based on calculated, experimental and laboratory data; 6 year warranty period with the actual service life of 12 years; Installation and comissioning of our equipment. 10 The total air flow rate fed to all EKOTON Air Diffusers in operation exceeds ft 3 /h

11 EKOTON AERATION SYSTEMS For more than 20 years EKOTON Industrial Group delivered more than 400 miles of air diffusers and continues this input increasing. Over 20 years of work we have gained the unique experience that allows us to offer customers only the most effective solutions. Reference of the Chief of wastewater treatment facilities and pump stations in Herzliya city (Israel): In November 2013 we launched the first section of the reactor with EKOTON tube air diffusers. The results exceeded all our most optimistic expectations. The quantity of consumed air as well as the energy was significantly reduced. Liquid saturation with oxygen was stable and uniform throughout the whole basin. After 2 months, without waiting for the end of 6-month period of supervision of air diffusers operation, as agreed earlier, it was decided to replace the diffusers installed in two other sections with EKOTON Air Diffusers, and that was done gradually. Today the entire reactor (3 sections) is equipped with EKOTON air diffusers and we are very pleased with the results obtained. The desired concentration of oxygen (approx. 2 mg/l) is maintained in all sections with much lower energy consumption. Most of the day (14-16 hours) we use one air blower ( ft 3 ) and during peak hours (8-10 hours) we use two blowers, whereas before the replacement of aerators we had to use 2-3 air blowers.
